How it works

The hydrated lime powder absorbs SO₂.
FLSmidth provides either a pneumatic solution, or a mechanical bin that meters hydrated lime powder into the raw material via a dosing system connected to the kiln feed.

The HLI system is a cost-effective solution for handling periodic fluctuations in SO₂ emission levels to remain within legal compliance limits. The hydrated lime can absorb up to 60% of SO₂; for higher reduction rates – up to 90% – FLSmidth's Gas Suspension Absorber (GSA) must be used.
